WATER-HEATER.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed April 2l, 1904. Serial No. 204,153.

To all whom, it may concern:

Be it known that I, ANDREW WINTER, a citizen of the United States, residing at West Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Water Heaters and Purifiers, of which the following is a specification.

My invention relates to improvements in water heaters and purifiers, and especially those in which exhaust-steam is used.

The object of my invention is to utilize the exhaust-steam from an engine or any steammachine for the purpose of heating the water, separating the oil and impurities therefrom, and purifying the water for use in boilers and thc like.

My invention consists of a closed chamber having within it steam and water pipes and steam and water chambers or spaces, steamexhaust inlet, steam-exhaust outlet, steamcondensing chamber in the steam-outlet, a cold-water inlet through the steam-exhaust outlet, steam-breakers or baiiie-plates, discharge-water pipes passing through the steamchamber and meeting the suction-pipe on the outside of the chamber and provided with suitable automatic water-supply regulator, gage, and other features.

My rinvention also consists in the construction, combination, and arrangement of the several parts, as herein set forth and claimed.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a horizontal longitudinal section on the line .fr x of Fig. 3, showing also a top view of the automatic water-regulator, water-receiver, Waterreturn pipe, water-circulating pipes, and gage. Fig. 2 is a longitudinal vertical section on the line y g/ of Fig. 3, showing parts in side elevation. Fig. 3 is a vertical cross-section on the line .e ,e of Fig. 2 looking to the left. .Fig 4 is an enlarged detail View showing the joint of sections of the inner shell.

l prefer to construct my improved water heater and purifier substantially as follows:

The outer shell 1 is preferably formed cylindrical in shape, with a fixed head 2 in one end and a removable head 3 in the other end. Mounted within closed chamber or shell 1 and secured to the head 3 I provide a receptacle 4, having water-spaces 5, 5, and 5b, separated from each other by steam-spaces 6 and 6a. The water-spaces 5, 5u, and 5b are connected together near their tops by water-circulating pipes 7 and 7 E, and the steam-spaces 6 and 6 communicate with the steam-space 8, surrounding the sides and one end of the receptacle 4, by means of openings 9 and steamtubes 10. VVithin the steam-spaces .I arrange a series of baffle-plates 11, and over the top of each steam-space 6 and 61L I secure steam deiiectors or spreaders 12. Exhaust-steam is` admitted through the steam-inlet 13 and circulates through the steam spaces and tubes, as indicated by the light arrows. The steamcondenser 14 is located at the top of one end of the shell and is preferably globe-shaped.`

The cold-water-supply pipe 15 extends into this steam-condenser and is provided on its inner end with a bell or dome shaped deflector 16. Above this dome in the cold-water pipe is a series of openings 17 to discharge jets of the incoming water and cause it to thoroughly commingle with and condense the outgoing steam. The steam-outlet, which also serves as the cold-water inlet, is also provided with steam and water breakers 18. Directly beneath the steam-outlet inthe steam-space above the water-space 5 is a water-receiver 19, preferably funnel-shaped, with a tube 20 eX- tending to near the bottom of the adjacent water-space and all`supported on a shelf 21, secured to the headB. The water-discharge pipes 22 lead out of each side of the waterspace through the steam-space and through the removable head and are joined together to the suction-pipe 23 upon the outside of the chamber. These pipes 22 being double, the area of the suction-pipe into which they discharge causes a slow travel of the water, whereby it is heated to a higher temperature than otherwise, and at the same time prevents any suction within the Water-heater.

A suitable automatic water-supply regulator 24 of any well-known construction is provided to maintain a given quantity of water at all times, and a suitable water-gage 25 is also used to show the stage or level of water.

When it is desired to utilize all of the escaping exhaust-steam for heating purposes, the incoming cold water is conducted directly into the lower part of the water-space through water-pipe 26, to which is connected a returnpipe 27 for the return of any exhaust-steam and its condensed product. This is regulated by valves 28 and 29. When condensing, the

steam-valve 28 should be open and valve 29 closed.I When using the steam for heating,

close valve 28 and open valve 29. I provide an enlarged chamber 30 in the water-pipe 26 to permit of the expansion of the return condensation from the-heating apparatus. Drainpipes 31, 32, and 33 are provided near the bottoms of the respective water-spaces for the removal of sediment. These pipes are regulated by suitable valves. (Not shown).

rIhe outer shell is provided at its top with suitable manholes 34 to permit easy access for cleaning andthe like and at its bottom with a drain-pipe 35 to carry off the oil and other scttlings, one end of the receptacle 4 being supported on wheel 37 and the other end and interior parts on the removable head 3. The entire inner structure is easily taken out for repairing by simply removing the bolts 36 and moving the structure forward on wheel 37 and wheels 38. The several sections of the receptacle 4 are out away at intervals and secured together by bolts 39, as shown in Fig. 4. Plate 4() is removably secu red to the steamcondensing chamber and permits access to the interior thereof.

The operation of my water heater and purifier is as follows: Introduce cold water from the water-pipe 15 into and through the condenser 14 and into receiver 19. The water passes down in the direction of the heavy arrows, depositing sediment in the bottom of water-space 5. The water circulates upwardly and passes through water-circulating' pipe 7 to the bottom of water-space 5, where further settling of sediment takes place. The water circulates around the steam-tubes in the water-space 5, whereby it is heated and passes upwardly and out through circulating waterpipe 7a to the bottom of water-space 5h, where any remaining sediment is deposited. The

water is heated to still higher temperature in the water-space 5b, and the clear and purified water rises and passes outthrough dischargepipes 22, as indicated by the heavy arrows, being still further heated while passing through the pipes in the steam-space. It is discharged from these pipes on the outside of the chamber into a suction-pipe 23, through which it is conveyed to the pump for use. As the water passes in the course described and as indicated by the heavy arrows the steam is admitted through exhaust-steam inlet 13 and circulates through the steam space and tubes in the manner indicated by the light arrows, heating the water by thus passing around and through it in the spaces and tubes, and at the same time coming in contact with the baffie-plates the oil is deposited thereon, drops to the bottom, and is drawn olf. As the steam passes upwardly through the steamspaces it is held from circulating' rapidly by the bafie-plates and defiectors until it reaches.

the outlet, where it is met by aconstant shower of water discharged from the cold-water-supply pipe, part of it discharging through the small openings, spreading over the dome, and

falling in a shower to the plate below and part of it passing through the dome. and thus the' outgoing steam is immersed with water and condensed. The water is dashed from the plate and again meets the steam and condenses it, immersing the steam as it passes from the outlet to the water-receiver. The `supply of water is so regulated as to maintain a uniform level vwith a substantially constant inliow of water, so that steam passing outwardly will be substantially all condensed for heating and purifying the water in the receptacle to be used in boilers and the like. By introducing the cold water into the condensing-chamber a vacuum is produced and relieves the back pressure from the engine. When the cold water is passed through pipe 26, it causes a vacuum and reduces the back pressure on the return heating system, and by providing chamber 30 in pipe 26 any remaining steam left will expand and produce a cushion, which retards the force of the water in the water-space and prevents the sediment from being disturbed. The cold water coming in sudden Contact with the heat of the steam will expand the water and relieve it of foreign matter, causing it to drop down through the receiver and deposit at the bottom of the water-space. As the exhauststeam enters the steam-space the steam is eX- panded and frees most of the oil therefrom, the latter dropping to the bottom and the former circulating through the steam-spaces and steam-tubes and the clear steam passing into the condensing-chamber.

The discharge-pipes 22 are provided with stuffingboxes 41, which act as expansionjoints in order to prevent straining or breaking. These pipes can be connected on the inside of the chamber at the bottom and when so constructed will require only one of the pipes extending through the head instead of two.

It will be seen that by an extremely simple and convenient construction and arrangement I am enabled to utilize the exhaust-steam for heating and purifying the water for use in boilers, also separating the oil, and when desired using the escaping exhaust-steam for heating and purifying the water.

From the above description it will be apparent that various changes in the construction may be made without departure from the scope and spirit of the invention as, for instance, the shape of the shell and receptacle may be varied as well as the manner of securing the parts together.

An important advantage which obtain is the arrangement by which the entire inner structure is removed by simply unfastening the removable head and pipe connections and drawing same forward.
